The corridors of the BioTechProm Research Institute smelled of boiled pearl barley from the cafeteria. Engineer Fedor sat with his head in his hands. A jewel beetle crawled on the lab table in front of him, shimmering in every shade of emerald and gold.
"Fedor, did you forget to pick up the youngest from kindergarten again?" Berta entered the lab as silently as a cat. She held a tablet with the spectral analysis results.
Berta was the ideal lab assistant. Always neat, unmarried, with a perpetually cool gaze and astonishing patience. Everything in her life was laid out in its proper place, while Fedor's resembled a quantum superposition.
"It's worse, Berta," Fedor groaned. "All three of them are coming to see me today."
"Who are the 'three'?" Berta raised an eyebrow.
"Wives. Ex-wives and current one. And five children. We need to discuss vacation schedules and..." He waved his hand at the beetle. "And why doesn't this beetle want to absorb infrared radiation, as the calculations said?"
The essence of the experiment
They were working on the Chitin-M project. Scientists discovered that the emerald beetle's shell possesses a unique nanostructure capable of not just reflecting light, but refracting it to create invisibility in a certain spectrum.
"If we understand how the beetle controls its pigmentation at the molecular level, we'll create radiation-resistant casings for interplanetary probes," the research institute director liked to say.
"Maybe he's just stressed?" Berta suggested, carefully touching the iridescent elytra with tweezers. "Just like you. Too many external stimuli."
At that moment, the lab door swung open.
"Dad! Gleb took my car!" A toddler of about five flew into the room, followed by a determined woman in a formal suit.
Fedor jumped up, tripping over the oscilloscope wire. The sensors howled. The jewel beetle, startled by the noise and sudden movement, suddenly flared with a blinding white light.
Berta quickly glanced at the monitor and froze.
"Fedor Petrovich... Look at the graph. The light pressure has jumped! It's not just reflecting, it's accumulating stress energy and converting it into kinetic momentum!"
Fedor looked at his ex-wife, his bawling son, the calm Berta, and the glowing beetle.
"So, to get the engine going, we just need to create the conditions for a total family scandal?" he whispered.
"Most likely," Berta nodded, smiling for the first time that day. "Congratulations, engineer. It seems your turbulent personal life has just paved the way for humanity to reach the stars."
